NEW CLASSIFICATION OF FRESH AND BRAKISH WATER PROSOBRANCHIA FROM THE BALKANS AND ASIA MINOR by PAVLE RADOMAN Faculty of Sciences, Beograd (31. 5. 1973) During the preparation of a monograph of Prosobranchia from the Balkan Peninsula, which were up to now usually put into the family , I arrived long ago to the conclusion that their cannot be correct if based on the shell characters only. To be able to discover and trace numerous phylogenetic relations­ hips between so many species, and to give their »natural« classifi­ cation into genera, families and higher taxa, it was inavoidable to work on the details of their anatomy. After a long time, many thou­ sands of traveled kilometers (I personally collected all my mathe- rial), and countless painstaking dissections, I have accumulated certain interesting results which I wish to present here. New system of genera and species mentioned in this paper was based primarily on the anatomical data, while the shell was used to distinguish the species within the same genus, and very seldom for the separation of related genera (this will be more extensively discussed in the mo­ nograph). The proposed classification is as follows:

SUPERFAMILY FAMILY SUBFAMILY Hydrobioidea Hydrobiidae Hydrobiinae Pyrgorientaliinae Orientaliidae Orientaliinae Horatiinae Sadlerianinae Pseudohoratiinae Islamiinae Graecoanatolicinae Pyrgulidae Pyrgulinae Chilbpyrgulinae Ohridopyrgulinae Micropyrgulidae Turricaspiidae Emmericiidae Lithoglyphidae Bythinellidae Lithoglyphulidae

The Family Bythiniidae does not belong to the superfamilyHydrobioidea. SUPERFAMMILY HYDROBIOIDEA (1) The same type of the radula in all families: the central tooth usually butterfly-shaped, with or without basal cusps; lateral tooth axe-shaped, with a relatively long »handle«; internal marginal tooth relatively broad, with an elongated, to the left (right, respectively) turned top; outer marginal tooth narrow in the middle, with a wi­ dened base and spoon-shaped top. (2) The stomach with a »crystalline style« on its pyloric end; (3) The same type of the nervous system: rather forward, be­ hind the pharyngeal mass, the bucal ganglia are located, then cere­ bral ganglia, usually with, rarely without a ganglionic thickening on the tentacle nerve; with cerebral ganglia, pleural ganglia are con­ nected by short connectives (sometimes without any connective); usually long, rarely shortened, pleuro-supraintestinal connective, and usually shortened, rarely a little longer, pleuro-subintestinal connective is present; sub- and supraintestinal ganglia are connected by long connectives with a single abdominal ganglion, and cerebral and pleural ganglia, by relatively long connectives, in the form of a triangle, with pedal ganglia; propodial ganglia (by shorter con­ nectives) - and metapodial ganglia (by longer connectives) are con­ nected with pedal ganglia; metapodial ganglia connected one with another by a long commissure; both (right and left) zygoneuries present; (4) The male reproductive system: from the seminal gland, lo­ cated along the upper side of the »liver«, goes' a long, very coiled, voluminous vas deferens, which becomes narrower near its end and enters a rather big accessory gland; on the end of this gland the ter­ minal part of the vas deferens continues (usually in zigzag), entering the penis and terminating on its point; penis usually simple, smooth or with outgrowths on its left side, rarely with more (two ot three) branches. (5) Female reproductive system: from the usually voluminous ovarium, located also along the upper side of the »liver«, goes a thin oviduct, which, after branching a gono-pericardial duct, beco­ mes wide and makes a »loop« (or a »clew«) leaning against the accessory gland (very rarely imbeded in the tissue of the posterior part of this gland); after coming out from the »loop«, the oviduct becomes slightly narrower and goes along the ventral side of the well developed accessory gland, terminating by a goonoporus on its top; this (vaginal) part of the oviduct broadly communicates with the accessory gland, being separated from it only by a longitudinal fold; a genital chamber present (very rarely lost); one or two semi­ nal receptacles also often present, however in some families lost.

Family HYDROBIIDAE (1) Usualy two basal cusps on the central tooth of the radula; (2) A characteristic tube-shaped caecal appendix on the oeso­ phageal end of the stomach; (3) A relatively long pleuro-supraintestinal, and a shortened pleuro-subintestinal connective; all ganglia usually black pigmented; (4) Two or one seminal receptacle (rsi, rsî), topographycally always located on the same places: rsi near the angle formed by the genital chamber duct and terminal part of the oviduct, and rs 2 near the end od the »loop«. (5) The oviduct in »loop« (or in »clew«) slightly to moderately widened, poorly glandulous, always black pigmented. Spread: brackish waters or fresh waters in the coastal regions of Adriatic and Anatolia (Turkey).

Subfamily Hydrobiinae

(1) Usualy two basal cusps on the central tooth of the radula; (2) One seminal receptacle (rsi).

Family ORIENTALIIDAE (1) Usually two, sometimes more, basal cusps on the central tooth of the radula; (2) A tube-shaped caecal appendix not present on the oesopha­ geal end of the stomach; (3) A rather long pleuro-supraintestinal, and a shorter (but still relatively longer than in Hydrobia) pleuro-subintestinal connective; (4) Two or one seminal receptacle (similar as in Hydrobiidae) (5) The oviduct makes a circular »loop« leaned against the po­ sterior part of the accessory gland. Spread: fresh calcareous waters — springs, streams, rivers, lakes.

Subfamily Orientaliinae

Two seminal receptacles (rsi and rsî), the first discharging in the oviduct near the angle of the genital chamber duct and the ovi­ duct, and the second one at the end of the »loop«.

Shell elongated, conical, with a mo- derately pointed apex; tumid whorls ( about 5 —■ regularely expan- \ 2 ding in width, though a little more at the begining than later, so that the shell has a slightly oval form; the aperture ovoid, coside- rably narrower at the top; margins of the aperture thin, including the columelar one also, which applies to the last whorl, so that the peristome is discontinuous; umbilicus barely slitlike. Measurements in mm: shell length 3,1—3,9; width 1,5—1,8 aper­ ture length 1,1—1,3; width 0,8—1,0 3 number of whorls 5—5 — 4 • Locus typicus: brackish spring Pontana, about 20 km, west from the town Split, Dalmatia. Hydrobia cissana n. sp. (Cissa — island Pag). Shell elongated, moderately pointed; tumid whorls (6—7) separated by a rather deep suture, very regularly expanding in width; aperture regular, eggsha­ ped, with rather thin margins, the outer one being gently curved, pe­ ristome continuous; umbilicus broadly slitlike. By the shell form similar to H. ventrosa, but a little smaller, although with more whorls. Compared with H. spalatiana, H. cissana is a little bigger, with less oval shell, relatively lower aperture, continuous columelar edge (peristome), larger umbilicus.

Locus typicus: Cave from which Sum spring comes out, about 4 km. west of town Struga, Macedonia. Parabythinella n. genus. Diagnosis of genus: Shell similar to certain species of the genus Bythinella, but the anatomical structure of new genus is clearly different: the left branch of the penis is much weáker and the gland which drains through this branch is much shorter than in species of the genus Bythinella, so that this gland does not get to the body cavity.

Anatomical and conchological characteristic, geographic distri­ bution and detailed drawings of the main anatomical features of every genus will be given in the monograph which is now in pre­ paration. Determination keys and photographs of every species will also be given. The proposed classification will, of course, be discus­ sed and explained in more detail. Besides, malaco-biogeographic re­ lations of the mentioned regions and phylogenetic relations of the discussed taxa will be revued. A special attention will be devoted to the process of spéciation as well as to the other theoretical que­ stions. If I would have enough matherial on my disposal (a certain amount I already have), I would also try to compare representa­ tives from the Balkans and Asia Minor whith those from Baycal lake and with some from the North America.. 26 Table 2 Ui »J h < O 73 s w 0i H D w Pi J h

NOVA KLASIFIKACIJA SLATKOVODNIH I BOCATNIH PROSOBRANCHIA BALKANA I MALE AZIJE

U ovom radu dat je nov sistem velikog broja vrsta i rodova iz grupe PROSOBRANCHIA koji naseljavaju slatke i bo¿atne vode Balkanskog poluostrva i Male Azije. Ovi rodovi i vrste do sada su najôesce ukljuéivani u jednu familiju, Hydrobiidae. Takva sistema- tizacija izvedena je gotovo iskljuöivo na osnovu karakteristika lju- sture. Medutim, odavno sam se uverio da su osobine ljuáture, kao sistematski karakteri, od ogranicenog znacaja i mogu posluíiti samo za razlikovanje srodnih vrsta iz okvira istog roda. Za sistematizaciju vrsta u rodove i viSe taksonomske kategorije neophodno je detaljno upoznati anatomsku gradu. Rezultat takvog rada je sistem koji se ovde izlaie. Dosadasnja familija Hydrobiidae podignuta je na rang superfa- milije HYDROBIOIDEA, koja je zbog znaèajnih anatomskih razlika odvojena od superfamilije RISSOACEA. U okviru superfamilije HYDROBIOIDEA izdvojeno je 9 familija, a za svaku od njih date su osnovne anatomske karakteristike, pri éemu su uzeti u obzir svi glavni organski sistemi. Familija Hydrobiidae podeíjena je na dve potfamilije, familija Orientaiiidae na 6 potfamilija, a familija Pyrgu­ lidae na 3 potfamilije. Za svaku potfamiliju takode su date osnovne anatomske karakteristike. PoSto je u radu spomenut veliki broj novih vrsta i rodova, date su i njihove kratke dijagnoze. Detaljnije obrazlozenje ove klasifikacije, crtezi i slike rodova i vrsta, kao i osvrt na filogenetske odnose ovih grupa i na draga teo- rijska pi tanja bice dati u monografiji koja se priprema.
